“…When the ambient temperature dropped to −40 and −50 °C, the discharge energy of PF6 was noticeably lower than FSI, probably due to exacerbated polarization effect. 31 As a result, although the delivered energy decreased with decreasing ambient temperature for both cells, FSI was able to deliver more energy compared with PF6, as shown in Figure 3c. For FSI, when self-heating was introduced, the cell was able to deliver 53.6% of the energy even when the ambient temperature was as low as −50 °C, and for PF6, it delivered only 30.7%.…”

Narrow operating temperature range and low charge rates are two obstacles limiting LiFePO 4 -based batteries as superb batteries for massmarket electric vehicles. Here, we experimentally demonstrate that a 168.4 Wh/kg LiFePO 4 /graphite cell can operate in a broad temperature range through self-heating cell design and using electrolytes containing LiFSI. Remarkable high-temperature stability with 6100 h of cycle life was achieved at 60 °C. With self-heating, the cell can deliver an energy and power density of 90.2 Wh/kg and 1227 W/kg, respectively, even at an ultralow temperature of −50 °C, compared to almost no performance for cells without self-heating. The heating process took 164 s and only 0.161% of the cell energy per degree of temperature rise. Fast charging at a 6C rate was achieved at all ambient temperatures. The total preheating and charging time was less than 12 min, and the cell finished 2500 cycles of 6C charging while still retaining 81.3% capacity.

“…Lithium plating is evidently revealed by postmortem analysis. [102][103][104] For example, the large silvery areas (lithium plating) are typically observed on graphite once disassembling pouch cell after longterm cycling at low temperature (Figure 7B). The uncontrollable lithium growth is revealed by scanning electron microscope images as denoted by the lithium whiskers and electrolyte drying.…”

Lithium-ion batteries (LIBs) have monopolized energy storage markets in modern society. The reliable operation of LIBs at cold condition (<0°C), nevertheless, is inevitably hampered by the sluggish kinetics and parasite reactions, which falls behind the increasing demands for portable electronics and electric vehicles. The electrolyte controls both Li + transport and interfacial reaction, dictating the low-temperature performance substantially. Therefore, the rational formulation of electrolytes is significant for realizing superior lowtemperature performance and broadening application niches of LIBs. Herein, we first discuss the kinetic limitations of low-temperature LIBs, highlighting the importance of electrolyte structure and interfacial chemistry. Then, the advancements for formulating subzero-temperature electrolyte are summarized with in-depth discussions about electrolyte formulation, solvation structure, interfacial chemistry, and low-temperature behaviors. Moreover, some opportunities for lithium metal batteries and the corresponding lowtemperature electrolyte are covered. Finally, the major challenges and future perspectives are outlined for low-temperature LIBs.

“…[12][13][14][15] Charging protocol has significant influence on the electrochemical performances of EES devices, including polarization voltage and cycle life for both LIBs and redox flow batteries (RFBs). [16][17][18][19] According to Teresa et al the side reactions in RFB could led to a charge (Faraday) imbalance between the catholyte and the anolyte, [20] which could decrease the system's capacity and impact the battery's performance permanently. By simply optimizing the charging protocol through raising the uppercutoff voltage, a remarkable 20-fold reduction of capacity fading (% h À1 ) was achieved.…”

With flowable slurry electrode architecture, lithium slurry battery (LSB) has the advantages of high energy density and independent energy and power, which can be used as an excellent energy storage device. However, its practical application is still hindered by multiple factors, including prolonged ion/electron passage, serious interfacial parasitic reactions, low energy efficiency, et al. The special electrode structure can influence the charge percolation pathway, reduce the apparent Li+ diffusion coefficient (), and further impact the battery performances. Herein, a special six‐stage constant current (SS‐CC) charging protocol for LSB is developed based on under different state of charges, that is, higher charging rate at larger . Comparing with other charging protocols commonly used in lithium‐ion batteries such as constant current‐constant voltage, the LSB charged by SS‐CC protocol not only shows higher energy efficiency, but also enhanced cycle stability. This is attributed to the better synergy between lithium desertion and plating, which kinetically reduces the parasitic reactions such as solid–electrolyte interphase accumulation, dead lithium, or dendrite generation. It is believed that this charging protocol design strategy can also be applied in other LSB systems.
